## How is Molarity different from Molality?

Both molarity and molality are measures of concentration, or how much solute is dissolved in solvent. Let's first get acquainted with a couple of terms. Solute - what gets dissolved Solvent - what the solute dissolves in Solution - solute and solute together Now, we can write out formulas for our two terms. Molarity(M) = moles of solute/ Liters of solution Molality(m) = moles of solute/ kg of solvent As evident from the formulas, molarity and molality equations both have the same top term. However their denominators are different. For molarity calculation, we need to find liters of solution and divide by it. For molality, we need to find kilograms of solvent. The units for molarity are mol/

## How To Arrange Alkenes In Order Of Stability?

To arrange alkenes in order of stability, we need to know that the most substituted the double bond is, the more stable the alkene is. Alkenes can be divided into four categories: monosubstituted (double bond is directly attached to one carbon), disubstituted (double bond is attached to two carbons), trisubstituted (double bond is attached to three carbons), and tetrasubstituted (double bond is attached to four carbons). Monosubstituted alkenes are least stable and tetrasubstitued alkenes are most stable. It is also important to note that to figure out substitution we focus on carbons directly attached to the double bond. However, many more carbons and functional groups can exist in the mole
